The events described in this small book are illustrative of much that took place in Vietnam after American troops were first committed in force in 1965; of heroic achievement and sacrifice, of human error, of experimentation and innovation, of a wily and elusive enemy, and of a new dimension of warfare afforded by the helicopter.These accounts serve as a preliminary record of the achievements of men who served their nation well, a preface to a full military history of the war that is in preparation. The narratives also serve as valuable lessons to soldiers pursuing lessons of small unit actions.
